Of course the Bible okays discrimination: not being yoked with unbelievers, kicking disruptive influences out of the church, discriminating against anyone you’re not married to when you’re looking for sex, etc. The question is what kinds it does and doesn’t condone, or is silent about. It’s pretty dang silent about placing strange kids in the custody of strangers.

If it were advertising itself as an adoption agency placing children in Christian homes, they’d have a case – since an agency adopting such a policy would do so with the eternal as well as the temporal welfare of kids in mind. Some evangelicals (not me) believe that Catholicism has enough baggage that it does not qualify as true Christianity – and the government is constitutionally barred from telling them that they’re wrong, an act that would impede their religious liberties.

But to single out one or a handful of religions is another matter. Why mention Catholics and not Buddhists, or Wiccans, or Scientologists? That would be unfair.
